UNIT 2 LESSON 4 - DEVELOPING POINT SLOPE FORM
WRITING THE LINEAR FUNCTION
What is the slope of the line?
What is the y-intercept?
Because we do not have an integer as the y-intercept all of the time, we need to know how to get the equation for a line a different way.[br][br]So how do we write equations for these graphs?
POINT SLOPE FORMULA
POINT SLOPE FORMULA IS FROM THE SLOPE FORMULA!
TO USE POINT SLOPE FORMULA TO WRITE THE EQUATION FOR A LINE, ALL YOU NEED IS THE SLOPE AND ANY POINT!
USING POINT SLOPE FORM PRACTICE
What is the slope of the line in the graph?
What would the equation be in point-slope form if you were using the point (-7,0)
Solving for y to get the equation in slope-intercept form would be...
What would the equation be in point-slope form if you were using the point (9,-4)
Solving for y to get the equation in slope-intercept form would be...
Does it matter which point you use to write your equation in point-slope form? Explain why or why not.
